New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...

How to manage 2 channel PWM with DMA - STM32L073

We try to generate audio signal with 2 PWM signals. We use TIM2_CH1 and TIM2_CH2 with DMA1 channel 5 and channel 3. This two PWM signals must be synchronized, but we noticed some delay between this 2 channels, which unfortunately is not constant. For...

In Rx Polling Mode, HAL_UART_Receive() is stuck in UART_WaitOnFlagUntilTimeout() waiting for the RXNE flag to get set in the UART's Status Register.

I'm using a STM32F407-Disc1 board, and my polled HAL_UART_Receive() is stuck waiting for the RXNE flag to get set in the UART Status register. Ironically, when using the STM32CubeIDE debugger and looking at the SFR registers for my UART, it looks li...
